应城Composite antioxidant B225

Antioxidant B225 plays a role in both processing stability and constant thermal stability. It is a complex synergistic stabilizer of main antioxidant 1010 and auxiliary antioxidant 168. Soluble in organic solvents such as benzene, chloroform, cyclohexane, ethyl acetate, etc., insoluble in water.

Appearance: White or light yellow crystalline powder

Solubility: Clear

Volatile matter: ≤ 0.2%

Transmittance: 425nm ≥ 96%; 500nm ≥ 97%

Antioxidant SK-168 content: 45.0%~55.0%

Performance advantages:

Composite antioxidant B225 is a classic mixture with a relatively high content of phosphite esters, which can meet the thermal stability of plastic processing. Within its application range, B225 has the following advantages:

Maintain the original melt index

Low stain

Significantly improves long-term stability

Characteristics and usage:

This product is a high-performance antioxidant widely used in polyethylene, polypropylene, polyformaldehyde, ABS resin, PS resin, PVC, PC, adhesives, rubber, and petroleum products. It has outstanding processing stability and long-term protective effects on polyolefins. The synergistic effect of antioxidant 1010 and antioxidant 168 can effectively inhibit the thermal and oxidative degradation of plastics. When used in combination with light stabilizer 662, light stabilizer 770, and light stabilizer 994 in polyethylene greenhouse film, it has good anti-aging performance. Composite antioxidants can be used in polyolefins, polyamides, linear polyesters, and ABS. The general dosage is 0.1% to 0.8%

Storage and Packaging:

Composite antioxidant B225 is non-toxic, non flammable, non explosive, non corrosive, and has good storage stability. Net weight 25kg/barrel (bag).
